Abstract

The invention belongs to the field of kitchen appliances, and in particular relates to a heat dissipation structure of a PCB circuit board and a cooking appliance having the same. The heat dissipation structure of the PCB circuit board includes: a base body, the base body is arranged inside the cooking utensil; a mounting plate, the mounting plate includes a board main body and a connecting part, the mounting plate is installed on the base body through the connecting part, and there is a gap between the board main body and the base body Setting: PCB circuit board, the PCB circuit board is arranged on the first side of the board main body, and the first side is the side of the board main body away from the substrate. In the heat dissipation structure of the PCB circuit board of the present invention, the substrate and the main body of the board are separated by air, thereby weakening the heat transfer effect between the substrate and the main body of the board, and there is not only an air isolation layer between the PCB circuit board and the substrate, but also The heat transfer from the substrate to the PCB circuit board is further reduced by the isolation of the mounting board, so as to weaken the influence of the high temperature of the substrate on the PCB circuit board, thereby improving the service life of the PCB circuit board.

Description

technical field [0001] The invention belongs to the field of kitchen appliances, and in particular relates to a heat dissipation structure of a PCB circuit board and a cooking appliance having the same. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] When cooking appliances such as ovens and microwave ovens are working, the whole machine is in a state of high temperature, and high temperature has a great impact on the working life of its internal PCB circuit board. In the face of the above problems, the existing solution is generally to place the PCB circuit board in a position with a slightly lower temperature in the whole machine. However, the PCB circuit board is still affected by high temperature, so that it often works under extreme temperature conditions, even Sometimes it works in a state where the local temperature exceeds the standard. Therefore, the service...
